I know this is probably a long shot from what I've read so far, but is it possible to customize the email that the friend receives after someone forwards it to them via the Fwd to a Friend pop-up form? Would love for it to say something along the lines of "first name thought you would be interested in this email" above the email they receive. Or has anyone thought of any hacks to achieve something like this?

Or being able to edit the actual Fwd to a Friend form would work too, such as the first example here where the person forwarding the email can add a personalized message: Support | Campaign Monitor

This is currently not available OOB. I agree that both the form and header above the forwarded email should be customizable. Would make this functionality actually usable as opposed to being all ghetto like it is.

I think I'm going to need to study this velocity coding that I have never heard of before until you mentioned it! I unfortunately know zero JavaScript But hopefully when I get a chance soon, I can test out your code. Thank you!
